Have you ever worried about melting or damaging a shirt, bag or other material when applying a heat transfer vinyl? I know I have – probably because I’ve melted an item or two in my crafting endeavors (okay, maybe more than that, but I’m not counting).

ThermoFlex Extra is THE solution to personalization with heat sensitive materials. It is available in 15 great colors:

Twelve of these colors can be layered for additional design options!

ThermoFlex Extra only needs to be pressed for short time periods at 310-315 degrees Fahrenheit on nylon, synthetic leather, leather and other materials. This means you can personalize those materials that were previously untouchable by any kind of heat activated product!

Each material should be tested first.

Prepress for 5 seconds (optional, test first)

Press for 3-5 seconds

Let cool and peel the backing off

Cover with a teflon sheet

Repress for 10 seconds

Using these steps you can press to nylon, synthetic leather, leather and many more heat sensitive materials. For polyester, press at 330-335 degrees Fahrenheit for 17-20 seconds (ThermoFlex Plus instructions).

As with most heat transfer vinyls, the standard (red cap) blade is recommended. This HTV comes on a thick plastic carrier that makes it easy to cut and weed.

Cut the design in reverse (mirror image).

When applying to a water resistant or moisture-wicking material, clean the area with rubbing alcohol and allow it to dry before pressing the HTV onto it.

Note from the manufacturer: Dye migration has occurred with low energy dyes in polyester and poly-bled fabrics.
